The sol-gel solution was mixed by tetraisopropyl orthotitanate (TTIP), acetonylacetone, distilled water and alcohol at various molar ratios and coated on p-type silicon substructure for titanium oxide formation. Then the CO2 laser annealing in air at powers of 0.5, 1.5 and 3.0 W in the defocus mode was performed on the coatings for studying crystallization of titanium oxide. The microstructure and...
The resistance of nanoporous dentin biomaterial to CO2 laser irradiation was investigated by experiment and simulation for potential tooth hypersensitivity treatment. The controlled parameters were laser power of 0.03–0.150 W, scanning speeds of 11.4–34.2 mm/s and focus/defocus modes for studying interaction between laser energy and dentin of human tooth. Most of dentin specimens were etched after...
A through-silicon-via (TSV) process is demonstrated on 28nm CMOS baseline with good electrical performance and low cost. TSV leakage, yield, C-V flat-band shift, Cu contamination, and reliability are significantly improved via process optimization. The preferred TSV processing could relax TSV stress and minimize keep-out zone (KOZ). In this study, we also address the impact of multiple-TSVs additive...
Two SMSD gate first planar CMOS devices were demonstrated. Vtn/Vtp= +0.49V/-0.48V were achieved by adjusting TiN to p-like metal and As I/I on nMOS. This enables the equivalent +/-0.2V low Vt target of N22 fully depleted CMOS technologies. Vtn/Vtp= 0.52/-0.55 were obtained by transforming PVD-TiN/Ti into n-like metal TiN/TiSix for nMOS and by Al I/I on TiN/Ti for pMOS. Al diffusion was facilitated...
Integration of high-k/metal gate stacks has been discussed in this paper. Pre-gate clean, interfacial oxide treatment, high-k and metal film deposition were investigated for optimized Jg-EOT. Various approaches such as HF vapor clean, surface hydroxylation treatment, and metal gate modification (such as interface treatment and high density top layer) were employed to improve the electrical properties...
Omnidirectional M-mode echocardiography(OME) can detect dynamic information from sequential echocardiography images. Temporal motion velocity and acceleration of a part of the cardiac structure contains the information about the composition offerees related to a heart. In this paper we present methods for detection of temporal motion velocity and acceleration of OME. Gray-time waveforms are rebuilt...
Human heart failure is a complex syndrome that can be initiated by a variety of clinical conditions and genetic factors. Gene expression profiling offers opportunities to study changes in transcriptional activity in heart failure samples of different etiologies. This paper evaluates machine and statistical learning models for supporting the identification of heart failure etiology based on gene expression...
To simplify the calculation of winding bar temperature for the condition monitoring of the water cooling stator of Three-Gorge hydro-generator, this paper calculates three of two-dimension thermal fields. Using the three fields simulates the different section along the axial direction of the generator. The total amount of heat taken away by water can be calculated by weighting the result of three...
It is well-known that tapered slot antennas (TSA) can operate over a wide frequency band. Some examples of these antennas have already been analysed and their performances are well-documented in the literature. In this category of antennas, one structure of current interest is the V-shaped TSA on a high dielectric constant substrate, reported by Simons et al. (see IEEE Trans. on Antennas and Propag...
